Question

1. Calculate the survival rate for each group in figure 1. Use the following formula: percent survival= (surviving rabbits/#beginning rabbits) *100

For example, if a group had began with 10 rabbits and only 3 survived, the percent survival would be 3/10 *100 or 30%. Which group has the highest survival rate? Which group had the lowest?

2. Use your results to write an overall conclusion to the Rabbit Island Experiment. Also develop an answer to each of Dr. Trudeau’s questions.

3. What is the dependent variable in the Rabbit Island Experiment? Also, list all of the independent variables you can think of in the experiment.

Answer 1

Answer 1

Rate of surviving rabbits

Group 1= 1/5*100= 20% Lowest
Group 2= 5/5*100= 100% Highest
Group 3= 3/5*100= 80%

Answer 2

Dr. Trudeau’s experiment shows that he was right about having bad living conditions can worsen the sickness of tuberculosis. At that time they didn’t know that tuberculosis could be control or even stop by having a healthy lifestyle. For example; exercising, resting, eating healthy and being outdoors.

Answer 3

The dependent variable is the number of surviving rabbits. This is the measureable and observed differences in the outcome of this experiment.

The independent variables would be the following:

1.inoculated with tubercle bacillus/healthy rabbits

2.confined or not confined

3.location of confinement

4.sun exposure

5.exposure to fresh air

6.physical activity/exercise

7.amount of food/nutrition
